Abstract

Objectives: To assess and compare the microtensile dentin bond strength (μTBS) and interfacial micromorphology of three universal adhesives.

Methods: 96 human molars were assigned to three universal adhesives: Single Bond Universal (SBU), CLEARFIL Universal Bond Quick (UBQ), and RE-GEN Universal Adhesive (REGEN). Adhesives were applied in self-etch mode. SBU and REGEN were applied following the manufacturers' instructions. UBQ was divided into two subgroups: one following the manufacturer's instructions (UBQ Short) and the other with an extended application time (UBQ Extended). Teeth were restored with nanohybrid resin composite. Specimens were divided into immediate and delayed subgroups. The delayed subgroups were stored for 6 months and subjected to 5000 thermocycles. μTBS was tested, and failure mode was analyzed. Interfacial micromorphology was assessed using a scanning electron microscope. The data were statistically analyzed (p⟨ 0.05).

Results: The adhesive choice, aging, and their interaction significantly affected μTBS. SBU exhibited the highest immediate μTBS, comparable to UBQ (Extended) and REGEN, and significantly higher than UBQ (Short). In delayed testing, SBU outperformed the other adhesives.

Conclusions: Aging negatively affected the μTBS of UBQ and REGEN, while SBU wasn't affected. The quick application concept of UBQ deteriorated its μTBS compared to the extended application time.

三种通用粘合剂牙本质微拉伸粘合强度和界面微形态的比较评估

目的评估和比较三种通用粘合剂的牙本质微拉伸粘接强度（μTBS）和界面微观形态：方法：将 96 颗人类臼齿分配给三种通用粘接剂：单粘接通用粘接剂 (SBU)、CLEARFIL 通用粘接快速粘接剂 (UBQ) 和 RE-GEN 通用粘接剂 (REGEN)。粘合剂以自酸蚀模式使用。SBU 和 REGEN 按照制造商的说明使用。UBQ 被分为两组：一组按照生产商的说明使用（UBQ Short），另一组则延长了使用时间（UBQ Extended）。用纳米杂化树脂复合材料修复牙齿。试样被分为即时亚组和延迟亚组。对μTBS进行测试，并分析失效模式。使用扫描电子显微镜对界面微观形态进行评估。对数据进行了统计分析（p⟨ 0.05）：结果：粘合剂选择、老化及其相互作用对 μTBS 有显著影响。SBU 的即时 μTBS 最高，与 UBQ（扩展）和 REGEN 相当，明显高于 UBQ（短）。在延迟测试中，SBU 的表现优于其他粘合剂：老化对 UBQ 和 REGEN 的 μTBS 有负面影响，而 SBU 不受影响。与延长应用时间相比，UBQ 的快速应用概念会降低其 μTBS 值。
